Paul R. Michel served as a Circuit Judge of the U.S. Court of Appeals for the Federal Circuit from 1988 to 2010, including a six year tenure as Chief Judge from 2004 to 2010. Here, he reflects on judicial treatment of patent eligibility law—from the Supreme Court’s decision in Mayo Collaborative Services v. Prometheus Laboratories, Inc. in 2012 through Friday’s set of opinions in American Axle & Manufacturing, Inc. v. Neapco Holdings LLC.

About once a month we provide an update on activity in important patent cases. In particular, we keep track of patent cases pending before panels of the Federal Circuit, where the cases involve at least one amicus brief. We also keep track of non-patent cases that attract amicus briefs, but only once those cases have been scheduled for oral argument. Finally, we also highlight panel cases we find important. You can find all of these cases in the “Other Cases” section of our blog. Today, with respect to these cases, we highlight two patent cases with new briefing, an argument recap in the only such case argued in April, and three upcoming oral arguments in these cases.
